Abstract: Abstract We compute all helicity amplitudes for four particle scattering in massless QCD with n f fermion flavours to next-to-next-to-leading order (NNLO) in perturbation theory. In particular, we consider all possible configurations of external quarks… read more here.

Abstract: We analytically calculate one- and two-loop helicity amplitudes in massless QED, by adopting a four-dimensional tensor decomposition. We draw our attention to four-fermion and Compton scattering processes to higher orders in the dimensional regulator, as… read more here.

DOI: 10.1103/physrevd.111.054037
Abstract: We present for the first time the second-order corrections of pseudoscalar(A) Higgs decay to three parton to higher orders in the dimensional regulator. We compute the one- and two-loop amplitudes for processes, A→ggg and A→qq¯g,… read more here.
